ELASTIC FABRIC.

Specification of Letters Patent.

Patented Apr. 23, E912.

To all whom it may concern. 7

Be it known that I, WALDEMAR Kore, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented an Improvement in Elastic Fabrics, of which the following is a specification. My invention relates to elastic fabric or webbing of parallel sided or tapering form and to the method of weaving the same, with the object of providing an elastic fabric suitable for use between parts under tension and in the gores of corsets, slippers, etc., and wherever such forms of elastic fabric are useful in the'arts and manufactures.

. In the article of my invention I provide.

opposite borders or edges of in-elastic fabric forming sewing sections by which the fabric is securely connected and anchored in place where used and between these sewing sections is an elastic part adapted to yield under the tension of use. The elastic part comprises warp threads, a minimum number of weft threads and elastic strands at an opposite angleto the warp threads, with their respective'ends woven in'and held by a part of the in-elastic fabric margins or sewing sections. The elastic part may be parallel 80 sided in a parallel sided fabric, or tapering in a tapering or parallel sided fabric. I prefer to employ for the elastic section an endless elastic strand preferably having a braided or twisted cover-of threads of suitable material and to weave this endless elastic strand preferably under tension back and forth with doubled ends through the elastic section, the doubled ends being, for an appreciable length or to the selvage t0 woven into the in-elastic marginal or sewing sections so as to anchor the same in eifectually for the strain and tension applied to the elastic section in use.

The elastic fabric of my invention may be of any width and there after cut up. It may be parallel sided or in tapering sections Where there are taperingwsections the same may be woven in reverse interlocking series and substantially. endless, adapted thereafter to be cut .up

into sections for use in gores of corsets, slippers, etc.

In the drawing, Fi parallel sided elastic re 1 is a plan of a abric formed according to my invention. Fig. 2 is a longitudinal section at the dotted line a: as of Fig. l in larger size. Fig. 3 is a cross section in larger size at the dotted line 3 y of Fig. 1. Fig. 4 represents by a plan a section of tapering elastic fabric with a V shaped elastic part and the doubled ends of the elastic extending to near the selvage. Fig. 5 is a diagrammatic plan illustrative of the method of manufacturing the tapering section of Fig. 4 in reversed interlocking series of any width and length. Fig. 6 is a plan of a parallel sided elastic fabric like Fig. 1 except in this case the elastic strands extend to the selvage. Fig.7 shows a parallel sided elastic fabric with a V shaped elastic part and Fig. 8 shows the V shaped elastic part with parallel sided sewing sections.

Similar letters and numerals of reference in the several figures indicate the same parts.

The elastic parts in Figs. 1, 4, 5, 6, 7 and 8 are shown as woven under tension of the elastic strands.

a a represent the inelastic marginal parts, and b the elastic parts. All of said parts a a and b are formed with warp threads of suitable material and with a minimum of weft threads. The parts a a are also formed with additional weft threads or filling of suitable material. The parts 6 preferably contain only the warp threads, a minimum number of weft threads and the'elastic weft threads, and the stretch of the elastic strands is at right-angles to the warp threadsand to the woven selvage of the webbing.

I may employ ,weft threads. of cotton or suitable materials with the elastic weft or filling threads, and I may apply appreciable tension to the elastic strands with the move ment of the shuttle in the weaving operation, but I do not limit my invention in this respect.

Figs. 1 and 6 illustrate that my invention may be embodied in a parallel sided webbing. Fig. 7 illustrates that the invention may be embodied in a parallel. sided webbing with a Vshaped elastic part, and Figs. 4, 5, and 8 illustrate that the invention particularly considered may be embodied in a V shaped part or member, where the opposite edges have sewing sections with substantially arallel edges, the elastic section b intermefiate thereof being 5 are specially sets, slippers,

25 threads entirely 45 binding also V shape, and with this latter form it matters little whether there be a selvage to the parts a a? or not, for the forms just on sidered and illustrated by Figs. 4:, 5 and 8 adapted for the gores of coretc., where a binding is put at the severed ends to prevent raveling of the threads and where the outer edges of the in-elastic marginal parts or' sewing sections 10 are sewed into opposite edges of the gores and edges covered.

The forms illustrated .in Figs. 1, 65nd 7 areparticularly applicable where there are parallel edges between and connected to which the elastic and in-elastic sections are to be connected. Fig. 5, diagrammatically considered, illustrates a manner of weaving the section shown in Fig. 4 or Fig. 8 wherein the said sections are woven reversed to be severed along their broad and narrow lines and also woven into interlocking series to be severed at the centers' of the sew; ing or in-elastic sections a a I may,

across the width of the woven, sections, as shown in Figs. 6, 7 and 8.

In Figs. 1, 4 and 5, the numberof warp threads is shown as increased in the in-elastic sewing sections while in Figs. 6. 7 and 8,

the number of warp threads and lalsb the number of weftthreads is increased in'the inelastic sewing sections, but I do not limit myself in these respects.

1 claim as my invention:

1. An elastic fabric woven with warp threads of suit-able material and a rubber thread or-strand as weft, or fillin and a certain pre-determined portion 0 the warp "woven with an additional filling of suitable 40 material so as to produce one or more in elastic sections.

2. An elastic fabric woven with warp threads of suitable material and a rubber thread or strand as filling or weft, and

the .warp threads, and an additional filling of suitable material binding the remainder.

if desired, extend the rubber wefta certain pre-determined portion of of the warp threads so as to produce an elastic webbing with in-elastic sections.

3. An elastic fabric woven with warp threads of suitable material and a rubber thread as weft or filling throughout the width of the fabric, and additional filling threads of suitable material binding certain pre-determined warp threads so as to produce one or more non-elastic sections. 4. A fiat strip elastic fabric, comprising an elastic center of elastic weft and in-elasthreads, and the'elastic strands formed from threads and elastic weft or filling a continuous piece of elastic doubled back and forth upon this and the doubled ends -woven appreciably into the adjacent edges of the in-elastic'or sewing sections.

8. A flat strip elastic fabric comprising a -V shaped elastic center and parallel sided inelastic margins or sewin sections.

9. A flat strip elastic abric comprising a V shaped elastic center and parallel sided inelastic margms o'r sewing sections, and in which the elastic strands are at right angles to the warp threads and extend across the elastic center and into the parallel sided inelastic margins or sewing sections for anchorage.

Signed by me this 14th day of September, 1911.
